The BC Racing ER series coilover for the Nissan 370Z features large external reservoirs front and rear, separate rebound and compression adjustment and a twin piston design. The external reservoirs hold much more oil than the conventional coilover, allowing the coilover to operate for a much longer period of time before overheating. The external reservoirs also house the secondary piston, which allows for the fine tuning of compression.

This is the perfect coilover system for the person who wants a high-end race coilover without the added costs, truly a budget buy!
